SPINDLE.

Application filed April 9, 1919.

To all wlw/2L if may concern:

Be it rnown that we, DAVID LEMOINE and GEORGE I. FoUnNinn, citizens of the United States, residing at Vhitinsville, in the county of llorcester and State of Massachusetts, have invented a new and useful Spindle, of which the following is a speciiication.

This invention relates to a spindle of the type described in our prior Patent No. 1,294A9d, issued to us February 1S, 1919.

In this type of spindle a plurality of bobbin-engaging arms are provided, yieldingly pressed outward to engage the wall' of the central recess in a bobbin.

It is the object of our present invention to improve the details of construction of this type of spindle to the end that it may e more easily and cheaply manufactured, and that it may be 'more eiiicient and reliable in use.

With this general object in view, an important feature of our invention relates to the provision of a plurality of bobbin-engaging armsp of improved design, and to the provision or an improved type of spring by the use of which uniform pressure on the several arms may be obtained,

@ther features of our invention relate to arrangements and combinations of parts hereinafter described and more particularly pointed out in the appended claims.

A preferred form of our invention is shown in the drawings, in which Figure 1 is an enlarged sectional elevation of our improved spindle;

Fig. 2 is a view similar to Fig. 1, but showing' the parts in operative position;

Fig. 8 is a transverse sectional view taken along the line 3-3 in F ig. 1, and

Fig. 11 is a detail perspective view of one of the bobbin-engaging arms.

Referring to the drawings, we have shown a spindle blade 10 having a driving whirl 11 secured thereto. The whirl 11 is provided with a recess 12 in its upper end, and a semi-circular groove 13 is preferably formed in the upper end of the whirl within the recess 12. A plurality of bobbin-en gaging arms 14 are assembled around the blade 10, the lower ends of the arms being rounded and seating in the groove 13. The arms 14s are lrept in position around the blade 10 by pins 15 in the whirl 11 interposed between adjacent arms.

Each arm 14 is provided with an out- Spe'cicaton of Letters Patent.

Patented Apr. 13, 1,930. Serial No. 288,694.

wardly projecting flange portion 1G which is engaged by the lower edge of an annular spring 17 located within the recess 12 and held in position by a cap 18 having a driving `t on the upper end of the whirl 11. rlhe cap 18 is preferably provided with a downwardly projecting shoulder 19 adapted to receive and center the spring 17, and this shoulder may desirably be headed over, as indicated in the drawings, to retain the spring in position thereon.

he spring is preferably formed of resilient sheet metal and the outer edge of the spring may be slightly upcurved to present a smooth bearing surface upon the flange portions 16 of the several arms 14. As the spring presses downward upon the flanges 16, the upper portions of the arms are forced yieldingly outward to the position shown in F ig. 1, such outward movement being limited by engagement of the arms with the inner edge of the cap 18. Then the bobbin B is placed on the spindle, the arms are moved inward to the position shown in Fig. 2, yieldingly engaging the bobbin to accurately center and drive the same.

7e have found the annular spring' 1T shown herein to be particularly adapted for use in this type of spindle, as it exerts uniform pressure upon all of the arms 1d, a result diflicult to obtain in our previous construction.

Having thus described our invention, it will be evident that changes and modifications can be made therein by those skilled in the art without departing from the spirit and scope of our invention as set forth in the claims, and we no not wish to be otherwise limited to the details herein disclosed, but what we claim is 1. In a spindle, in combination, a blade, a whirl, a plurality of arms surrounding said blade and seated on said whirl, each arm having an outwardly extending portion, a cap tit-ting the upper end of said whirl, and an annular spring formed of resilient sheet metal engaging the under side of said cap, the continuous outer portion of said spring also engaging the upper face of the outwardly extending portion of each arm near its outer edge, and acting to move said arm yieldingly away from said blade, said cap limiting such outward movement and preventing displa ement of the parts.

2. ln a spindle, in combination, a blade, a

face of the outwardly proj eeting portion of each arm to yieldingly force said arm away l0 from said blade. Y

In testimony whereof we have hereunto affixed our signatures.
